You are trying to install ruby-2.6.3 on heroku-20

I have tried changing the gemfile to an earlier version and then pushing again but it does not seem to work. Here is the code. Any ideas?

Not sure I have posted in the correct format, this is my first SO post.

Any help would be appreciated, my command git push heroku master generates that output.

haohaobaozhi has the perfect answer here.

heroku stack:set heroku-18

I was having the same issue as OP and setting the stack to Heroku-18 solved the issue. This might be a common occurrence for those following the "Learn Enough Ruby On Rails To Be Dangerous" Book.

remote:  !     You are trying to install ruby-2.6.3 on heroku-20.
remote:  !     
remote:  !     Ruby ruby-2.6.3 is present on the following stacks:
remote:  !     
remote:  !     - cedar-14
remote:  !     - heroku-16
remote:  !     - heroku-18

Currently supported Ruby version for heroku-20 can be seen here:
https://devcenter.heroku.com/articles/ruby-support#supported-runtimes

2.6.6, Rubygems: 3.0.3
2.7.2, Rubygems: 3.1.4
3.0.0, Rubygems: 3.2.3

The list will change with time (new ubuntu/heroku releases, new Ruby versions release, ...)

Update your ruby version (and make sure your project is compatible with the new ruby version).
